What is Demand Response?
• Management of electrical consumption
• Active alleviation of grid stress
• Load Shedding during peak demand periods

The Shocking Truth!
• It is estimated that a 5% lowering of demand would result in a
50% price reduction during the peak hours of the California
electricity crisis in 2000/2001.
• If demand continues to grow unabated, to meet future demand
will require 1,300 new power plants supplying 400 GW by 2020.
• It’s not just big corporations driving up demand… It’s you too!

Communication enables efficient energy use
EnviroGrid’s swarm logic ensures that loads:
Communicate and cooperate with each other
Use energy efficiently while maintaining occupant comfort

IP enabling edge devices leads to energy efficiency
• The EnviroGrid™ Controller is an IP-enabled edge device which
can be easily integrated into an existing network infrastructure.
• Built-in On-Demand portal to report and manage operations of
HVAC (edge device) equipment – API’s to integrate with BAS
• Monitor and manage fine grained load energy information
• Organizations can better understand energy use of individual
nodes (HVAC) on the network, schedule usage times, monitor
efficiency and proactively maintain the infrastructure

Swarm methods for Demand Response
Building 1
Building 2
• Self configuring mesh network
uses swarm logic to load
balance all connected loads
with minimal to no impact to
occupant comfort
• No need to worry about
thermostat setbacks, swarm
logic is adaptive and self

Real-Time Control and Reporting down to the level
of each load is a “must have” to confirm activity
Critical for successful DR testing, event confirmation
IP “edge devices” simplify making the invisible… visible!

Specific lessons from case study
Implementation costs – and
benefits can vary dramatically
by type of load
Baseline
DR
Real-time control and
verification of DR activity is key
Invasive DR causes negative
occupant reactions
Swarm load-balancing less
invasive than thermostat
setbacks
IP-based connectivity simplifies
& reduces implementation
costs
